The lever 22h), carrying the pawl 226, is arranged to be engaged by-the eccentric 23:), carried by the tight pulley 15, so that at each oscillation of said pulley during the knitting; of the heel or toe pocket said eccentric .235. clients the reciprocation of the pawl 226. to rotate the ratchet 225, and its sprocket 220. to progress the pattern chain 216. Said shitting loicr 190, is normally held in its right hand position with respect to Fig. I, by the spring 240. which encirples the rod th between said shifting lever 190, and the collar 242, adjustably secured on said rod.

The rod 206, is secured in the brackets 245, and 246, extending respectively from the bed plate 1, and the bearing frame 3, and is provided with a collar 248, between which and the bracket 246, the lever 250, is loosely mounted and extends through the eye 251, of the pawl 27. Said. lever 2:30, is arranged to lift. the pawl 12?, ut oi engage ment with its ratchet 28, when the machine is adapted to knit the heel and toe pocket, by being engaged and lifted by the. up wardly curved arm 252, which is carried by the shifting level 190, and which extends beneath said lever 250.

The cant cylinder 9, may be provided with the. usual lifting and depressing pickers, having any convenient form of latch (omitted from the drawings.) arranged to be tripped by the picker latch cam which is adjustably secured in the lever 256, pivoted centrally to the bracket 258, on the bed frame I. Said cant 2:35, is normally held out of the path of the picker latch mechanism by the spring 260 The lever -6, is provided with the arm 257, arranged to be engaged by the. centrally pivoted lever 262, which in turn is. en gaged by the lever 264, secured on the rock shaft 265. Said rock shaft 265, is jonrnaled in bearings 266, and 267, in the hanger 43, and is provided with the lever 2T0, extending over the sprocket 220, and in the path of the high link 21?, on the pattern chain 216, Therefore, the lever 270, is uplifted by said high link 217, and the cam is thereby shifted toward the cam cylinder 9, and into the path of the picker latch releasing mechanism.

The operation of the machine is follatiug needles. and shi "is the lever 190, to the left lowsz---The machine is rotated to knit the leg of the hose. which .is drawn down by the takeup mechanism. and in its descent engages and rotates the brush roller 85. which is connected to progress the nnmsuring chain When the ankle is reached, the high link 5.7. on said chain 52, uplilts the menu her lot). and rccks the lever 95, to lower the pawl .47, into engagement with the low tooth ill, of the ratchet 23, to start said ratchet so that its teeth 30, may he engaged by subsequent mciprocations of said pawl until another low tooth 31, is encountered 28, the chain 52. forcible and rapid movement until the high side link 58. has raised the lever llfi. to set the stitch length regulating device to fashion the ankle. 'lhe, uwasurlng chain 52, is then prcgressed again by the brush roller :55, until the high link 56, enctmnters the pin 183, and trips the belt shifting mechanism to shift the belt to the loose pulley it), as shown in the drawings, and the machine stops. The stopping of the machine ccutrots the locaticu of the heel pocket, and the operatt r then resets the stitch length reguinechanism, raises the half back with respect to Fig. l. to engage the oscilla tory clutch disk 1?, with the tight pulley 15, which auses the cam cylinder 9, to oscillate to form the heel pocket, during which time the pattern chain filth is progressed, while the measuring chain 5;", remains idle. 'hcn sutlicieut needles have heen raised by the lifting piclt rs. the high link 217, on the pattern chain 21 encounters the lever 2T which rocks the picker latch cam 255, into the path cf the picker latch mechanism, (not shown.) to release the depressing pickers, which depress the raised pocket forming needles down into action. \lhen all of the raised pocket forming needles have been depre-scd the hin'h link :215, on the pattern chain 216. nplifts the pin 20%. which releases the latch piece it/Ii. from the notch 305, and the lever-100. is again returned to its normal p: sitiou by the spring 30 and the machine is again brought to rest. The operator then shifts the belt to the tight pulley l5, and the machine is rotated to knit the foot, the measuring chain .32. being: progressed as before. until the high link 57. encounters the pin 183. to shift the belt to the loose pulley it. which stops the machine and controls the hcation of the toe pocket. The operator again raises the hall ha k needles. and shifts the ltX'tl' l tl, to the pcsit'ion to oscillate the cam cvlindcr t to knit the tre pocket. \Vhcu the maximum number of needles have been raised the high link 21?, shifts the latch ram 25?). to release the depressing pickers. When the pocket forming needles have all been depressed the high link 215,releases the lever 190, which is returned to its normal position by the spring 205, and the machine stops ready to start another stocking.

Hitherto in the production of string-work hosiery theinsertion of the pockets for the heels and toes of the stockings has been controlled according to course measurement with the consequent irregularity of the lengths of the stockings, making it necessary to sort and match all hosiery thus produced. According to the invention which I have thus described, string-work hosiery is produced in which the insertion of these pockets is controlled exclusively by actual length measurement, thus doing away with the nece sity of sorting and matching the stockings produced by the machine.

I do not desire to limit myselfto the precise details of construction and arrangement herein set forth, it is obvious that various modifications may be made therein, without departing from the essential features of my invention.
